SOURCE: Coolant fan stays on after

There's a thermostat control switch that lets the fan run after engine shutdown to bring the coolant temp down to an acceptable level. If the fan continues to run, this switch has gone bad. Any major parts store, or a Lincoln dealer, can sell you a replacement switch and show you a diagram that will let you locate and replace the bad one.

SOURCE: i have a 2006 vw jetta 2.0t and the fans stay on even after the ignition is off and key is out, will run until the battery is dead. I have replaced the coolant sensor and the computer sensor on the ov

The fans are run by rad temperature, not engine temp on a VW.Somewhere on the rad you should see a wire harness plugged into it.That is a thermo-switch which turns the fans on and off based on coolant temp in the rad. My car is a lot older than yours but this switch is virtually hidden on the bottom driver's side of the rad. It has 3 wires going into it.There could also be another sensor attached to the engine block or head to monitor engine compartment temps after engine shut off. This will turn the fans on or off as well based on air temp in the engine compartment.

Engine overheating i have replaced the radiator has plenty of water


replace thermostat.then bleed coolant system, this is how you do it.fill the cooling coolant system with 50 / 50 dexcool and water to raise boiling point,straight water will evaporate boil away cause engine to overheat catch fire thats why you need 50 / 50 mixture antifreeze and water.to bleed coolant system first fill coolant system until coolant stay at the full cold mark on the the coolant overflow jug,then you start engine allow it to idle,place the heater and ac control in any ac setting except max and the temperature control to the highest setting,run engine until lower hose to water pump is hot. with the engine hot run the engine speed up to 3000 rpm and allow it return to idle, repeat this 5 times. slowly open the bleed valve on the thermostat housing or look for bleed valve at the water pump heater hose.open bleed valve for 15 seconds to expel any trapped air.then top off the coolant as necessary,and when top radiator hose hot thermostat open up.keep adding cooling to overflow until coolant level stop at full cold mark dont over fill coolant.if engine seem like overheating while looking at cooling gauge turn off engine wait a while until cool off add more coolant until coolant level stay stable and dont drop any.when open radiator overflow cap use large rag over the radiator cap to keep from getting scald open radiator cap a little at a time but dont open radiator cap until engine cool down first.replace the radiator overflow cap, thermostat,and engine coolant temperature sensor and check the cooling fans fuses and relays see what happens.

Why is my car overheating?


You might have a clogged radiator. If so replace the radiator. I would first replace the thermostat as it might be bad. When they go bad they usually stay stuck in the closed position. When closed there is no flow of water to or from the radiator. You can check the thermostat by removing it, it is located on your upper radiator hose, the return hose. To check it boil a pan of water and and using a pair of pliers hold the thermostat in the hot water. If the thermostat is bad it will not open. Hope this helps.

IT KEEPS OVERHEATING


REPLACE THE THERMOSTAT AND RADIATOR PRESSURE CAP.IF COOLANT LOW, ADD MORE COOLANT THROUGH COOLANT OVERFLOW UNTIL COOLANT LEVEL IN THE COOLANT OVERFLOW STAY AT FULL COLD MARK.REASON POUR COOLANT THROUGH COOLANT OVERFLOW MOST GM CARS DONT HAVE RADIATOR CAP.WHEN YOU GET COOLANT LEVEL OKAY, CRANK CAR LET IT IDLE UNTIL ENGINE GET HOT BUILD UP PRESSURE THEN TURN OFF CAR.CHECK FOR COOLANTS LEAKS AT THE RADIATOR HOSES,CHECK FOR LEAKS AT THE RADIATOR, CHECK FOR LEAKS AT WATER PUMP WEEP HOLE IF YOU SEE COOLANT LEAKING FROM WEEP HOLE REPLACE WATER PUMP. IF CAR OVERHEATING WHILE IDLING YOUR COOLING FANS NOT WORKING CHECK COOLING FANS FUSE AND RELAYS.IF FUSE AND RELAYS OKAY THE ENGINECOOLANT TEMPERATURE SENSOR BAD.

DODGE CARAVAN 2007 AND CODE PO480 + PO562 + PO700 AND FAN COOLING REST OPEN WHEN THE KEYS NOT IN CONTACT THANKS


I just had the same codes a week ago. P0562 & p0700. Found that they were both related to a battery with a dead cell. The p0562 (low voltage code caused by no good battery) causes the transmission control module (p0700) to not receive the correct voltage and act up when drawing power from the battery due to dashboard, starter, etc. drawing from battery as well, With the keys in the ignition. I changed the battery to a new one. Removing the battery will reset the codes and with the new battery the codes may not re-appear, provided there are no other codes pending that could be causing the p0700 code. Some conditions you may experience are 1) no start 2) clicking from the tcm 3) clicking from the starter 4) the dashboard lighting having a life of its own coming on and off, dimming, etc. note: when this happened to me (all of the above) I tested the battery and it was ok, but the problem existed until the New battery was installed. Still runs good now

Engine overheating


The coolant flush on radiator doesn't do any good. Since you have changed all the key components and still gotten overheated, then the root cause of the problem is the radiator. It got clogged up in small tubes blocking coolant flow. No matter how good the water pump is working but the radiator got clogged up, coolant is not circulating therefore the heat from the engine can't be dissipated to the radiator. Replace your radiator, don't even think about rebuild it. It has been used for 11 years. Make sure to have the correct coolant/water ratio to keep radiator life for years. Good luck.
